Setting active line style

[stanleypaseur]

I have a revit file that has several different line styles. I am trying to write a C# routine that will create a large schedule. The schedule is in a detail view so all elements are detail lines and text. I searched the API help file and found "public Element LineStyle { get; set; }". I see that is a member of the  "CurvedElement" class. I am beginning to learn C# and the API calls. Can someone show me a couple of lines of how to call the appropriate method to set the active line style. I have line style "LineWt2" and "LineWt6". I want to the active line style to be "LineWt6" when the detail line is drawn. Your help greatly appreciated.

Another great resource to help while you're learning is the building coder github here:

Searching for linestyle results in a code sample of exactly what I believe you're looking for

// Find existing linestyle.  Can also opt to
      // create one with LinePatternElement.Create()

      FilteredElementCollector fec 
        = new FilteredElementCollector( doc )
          .OfClass( typeof( LinePatternElement ) );

      LinePatternElement linePatternElem = fec
        .Cast<LinePatternElement>()
        .First<LinePatternElement>( linePattern 
          => linePattern.Name == "Long Dash" );

Thanks for the information. I do not think this will solve the issue. I know what linestyles are available in the project. I have linestyles "Solid-wt-2", "Solid-wt-3", "Solid-wt-4" and "Solid-wt-6". I am trying to create a schedule and to make it easier to read I would like to have every 5th line "Solid-wt-6". So I need to be able to set the linestyle before creating the line. I am using the following method to create the line.

Line lineOne = line.CreateBound(double point1, double point2);

there isn't a method to set the linestyle beforehand. Just make the line and set the linestyle for that line.

                XYZ pt1=new XYZ(0,0,0);
                XYZ pt2 = new XYZ(2,0,0);
                Line lineOne = Line.CreateBound(pt1, pt2);
            Autodesk.Revit.DB.View detailView = doc.ActiveView;
            Category LinesCat = doc.Settings.Categories.get_Item( BuiltInCategory.OST_Lines);
            Category SolidW6 = LinesCat.SubCategories.get_Item("solid-wt-6");
            GraphicsStyle solid_wt_6 = SolidW6.GetGraphicsStyle( GraphicsStyleType.Projection)  ;
            using (Transaction t = new Transaction(doc, "place line"))
            {
                t.Start();
                DetailCurve detailLine = doc.Create.NewDetailCurve(detailView, lineOne);
                detailLine.LineStyle = solid_wt_6;
                t.Commit();
            }

Thanks very much for the help. I do not think I would have every thought use "Category". Still learning ( just started about a month ago).
